Dozens of children with disabilities are being pulled out of West Australian schools by parents who say they are not getting enough support in the classroom.

Key points:

William Anthony, 16, has been pulled out of school and is going to work with his father instead

His parents don't believe William's autism needs are being adequately met at his high school

People With Disabilities WA has been working with 40 other families in the same situation

Disability advocates argue inconsistent resourcing means schools across the state are failing some of their most vulnerable students.

The arrangement for Kevin and William Anthony to work together in a Broome truck yard may appear to be a heartwarming example of the bond between a father and his autistic son.

In reality, it was a situation borne out of desperation.

William's parents removed him from Broome Senior High School earlier this year after he began displaying violent and aggressive tendencies, predominantly towards his mother.

The 16-year-old would often leave the house happy and calm but return home on edge.

Andrea Anthony believed her son learned the habits because children with disabilities were taught in classrooms adjacent to students with serious behavioural problems and also shared an outdoor area where William was exposed to violent altercations.

"What was happening around him at school was not appropriate — it's thug, bullying behaviour," she said.

"That's why, in order for him to be safe and to not exhibit those behaviours, we needed to keep him out of school."
